One of my servers at work leads a very light life: it is our main backups server (so it has a I/O spike at night, with little CPU involvement) and has some minor services running (i.e. a couple of Tor relays and my personal email server — yes, I have the authorization for it 😉). It is a very stable machine… But today I was surprised: As I am about to migrate it to Debian 13 ( Trixie ), naturally, I am set to reboot it.
